Metadata: England and Wales - Shellfish Classification Zones of England and Wales
Abstract:
Map of Bivalve mollusc (shellfish) classification zones. Available on Magic, Spire and Cefas website. Bivalve mollusc (shellfish) harvesting areas are classified according to the extent of contamination shown by monitoring of E. coli in shellfish flesh. Treatment processes are stipulated according to the classification status of the area. The classification categories are: Class A (80% of samples must be = 230 E. coli/100g; all samples must be less than 700 E. coli/100g) - molluscs can be harvested for direct human consumption Class B (90% of samples must be = 4600 E. coli/100g; all samples must be less than 46000 E. coli/100g) - molluscs can be sold for human consumption: - after purification in an approved plant, or - after re-laying in an approved Class A re-laying area, or - after an EC-approved heat treatment process. Class C (= 46000 E. coli/100g) - molluscs can be sold for human consumption only after re-laying for at least two months in an approved re-laying area followed, where necessary, by treatment in a purification centre, or after an EC-approved heat treatment process. In all cases, the health standards in Annex III of EC Regulations 853/2004 and the microbiological criteria adopted under EC Regulation 2073/2005 must be met. Molluscs must not be subject to production or collected in prohibited areas. There are two classification systems in England and Wales: ( 1.)the annual or "temporary" classification system ( 2.)the long-term classification (LTC) system. New areas are initially given annual/temporary classifications until they meet the criteria for an LTC. Harvesting sites that do not meet LTC criteria are automatically classified under the annual/temporary classification system. Classification: Class A=1, Class B=2, Class C=3, Prohibited=4, Long Term Class B=5, Seasonal Class B/Class C=6, Seasonal ClassA/Class B=7

| Internal code | Internally assigned metadata identifier | 10529 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | England and Wales - Shellfish Classification Zones of England and Wales |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFASb1d8dc6c-8874-41fe-a812-a748af5d4a4a |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS79 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1990-01-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2099-01-01 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 10 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | quarterly |
